AXLE-GAGE.

SPECIFICATION forming part of Letters Patent No. 267,995, dated November 28, 1882. Application filed April 8, 1882. (No model.)

A A represent two segments of an ordinary axle. The gage and set B is a single bar of metal, made rather narrow, and is perfectly straight for about two-thirds its length. Then it is inclined at one end at a slight angle downward for a short space, as at B, and then terminates in a shprt straight end, B. On this bar set four sliding gaging-pegs, a a a a,

each held where set by a central thumb-screw,

= c, as shown. These pegs vary in length somewhat. Two are double-pointed and two singlepointed, as shown. The bar is divided into and will be marked or stamped into spaces, and with indicating-figures thereon. The slant B will be divided into one-quarter-inch spaces, for it is by this slant mainly that the work is accomplished. As an example, and as shown in Fig. 1, the bar is held under the axle A, the gaging-peg a is set on the first quarter notch or space on' the slant B, the point setting against the axle-arm, the peg a on the straight part of barB is set against the shoulder of they axle on its arm and close thereto, and peg a is at the extreme end of the taper of the arm, and peg a is on the straight end B, its point away from the axle ,or, to explain more clearly, when it is used to get the taper of both ends of an axle alike the bar is held or arranged unr set against the under side of the extreme end of the arm, then peg a is set against the outside of shoulder b, and if the taper is one-quarter inch it is set in that notch of slant B, about as shown in Fig. 1. After peg a is set a and a give the pitch of one end. Then the bar is turned round end for end, and the other axlearm made to conform to set of the pegs without moving them at all. The gather is now got by holding the bar in front of the axle, and which is made to conform to the set of the pegs, and which remain in precisely the same position on the whole bar as when getting the taper, except that the other ends of ,the pegs are pointed to the front of the whole axle, bringing pegs a, a, and a against the axlearms, peg a pointing away from it. This gives the exact gather necessary to make a wagon track just right, no other appliances being necessary than those before described. Thus by this very simple device the set and gather of an axle can be got without moving the sliding gage-pegs after once being set to the taper of said axle.

I claim- The'long narrow bar B, having the slanting part B and straight end B, and with the movable gaging-pegs a, a a and a thereon, said bar being divided into suitable measurin gspaces, and in connection with said pegs giv witnesses. ROBT. BOYCE.
